<h3>Method Details</h3>
<div class="method">
    <code class="details" id="close">close()</code>
  <pre>Close httplib2 connections.</pre>
</div>

<div class="method">
    <code class="details" id="create">create(body=None, x__xgafv=None)</code>
  <pre>Creates the given topic with the given name.

Args:
  body: object, The request body.
    The object takes the form of:

{ # A topic resource.
  &quot;name&quot;: &quot;A String&quot;, # Name of the topic.
}

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # A topic resource.
  &quot;name&quot;: &quot;A String&quot;, # Name of the topic.
}</pre>
</div>

<div class="method">
    <code class="details" id="delete">delete(topic, x__xgafv=None)</code>
  <pre>Deletes the topic with the given name. Returns NOT_FOUND if the topic does not exist. After a topic is deleted, a new topic may be created with the same name.

Args:
  topic: string, Name of the topic to delete. (required)
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format

Returns:
  An object of the form:

    { # An empty message that you can re-use to avoid defining duplicated empty messages in your project. A typical example is to use it as argument or the return value of a service API. For instance: service Foo { rpc Bar (proto2.Empty) returns (proto2.Empty) { }; }; BEGIN GOOGLE-INTERNAL The difference between this one and net/rpc/empty-message.proto is that 1) The generated message here is in proto2 C++ API. 2) The proto2.Empty has minimum dependencies (no message_set or net/rpc dependencies) END GOOGLE-INTERNAL
}</pre>
</div>

<div class="method">
    <code class="details" id="get">get(topic, x__xgafv=None)</code>
  <pre>Gets the configuration of a topic. Since the topic only has the name attribute, this method is only useful to check the existence of a topic. If other attributes are added in the future, they will be returned here.

    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # Response for the ListTopics method.
  &quot;nextPageToken&quot;: &quot;A String&quot;, # If not empty, indicates that there are more topics that match the request, and this value should be passed to the next ListTopicsRequest to continue.
  &quot;topic&quot;: [ # The resulting topics.
    { # A topic resource.
      &quot;name&quot;: &quot;A String&quot;, # Name of the topic.
    },
  ],
}</pre>
</div>

<div class="method">

  <pre>Adds a message to the topic. Returns NOT_FOUND if the topic does not exist.

Args:
  body: object, The request body.
    The object takes the form of:

{ # Request for the Publish method.
  &quot;message&quot;: { # A message data and its labels. # The message to publish.
    &quot;data&quot;: &quot;A String&quot;, # The message payload.

Each key should be globally unique. The &quot;host&quot; portion is called the &quot;namespace&quot; and is not necessarily resolvable to a network endpoint. Instead, the namespace indicates what system or entity defines the semantics of the label. Namespaces do not restrict the set of objects to which a label may be associated. Keys are defined by the following grammar: key = hostname &quot;/&quot; kpath kpath = ksegment *[ &quot;/&quot; ksegment ] ksegment = alphadigit | *[ alphadigit | &quot;-&quot; | &quot;_&quot; | &quot;.&quot; ] where &quot;hostname&quot; and &quot;alphadigit&quot; are defined as in RFC 1738.
